てなることを特徴とする給紙装置。[Claims for Utility Model Registration] A layered sheet that has a friction member and a feed roller that rotates close to the friction member, and is closest to the feed roller among the layered sheets that are fed upstream of the feed roller in the feeding direction. In a sheet feeding device, the feeding roller feeds out only the sheet that has been removed by the feed roller, and brakes other sheets by the friction member to prevent the other sheets from being fed. Consisting of a cylindrical body formed by connecting circular arcs that are in contact with a base circle coaxial with the central axis in the longitudinal direction and have a radius larger than the radius of the base circle, the friction member is arranged at a predetermined angle around the central axis. Rotate it,
A paper feeding device characterized in that the surface facing the feed roller is switched.
